Concern for 'filthy' Origin star as injury strikes again

Tom Gilbert could potentially face another stint on the sidelines after he was assisted off the field in the Dolphins' trial match loss to the Warriors.

The lock came in hard to tackle centre Rocco Berry but the Warriors outside back stepped inside, with Gilbert falling awkwardly despite no contact.

Gilbert stayed on the ground and put his hands on his face in agony.

"It looks like the knee," league great James Graham said on Fox League. 

"Aw dear, he looks in some strife ... he comes out (to tackle), he screams, it doesn't look great, he clutches at it straight away."

Any serious injury would be horrible news for Gilbert after he dislocated his shoulder for Queensland in Origin I.

The injury meant Gilbert only played 11 games for the Dolphins in their debut campaign.

After medical staff attended to Gilbert, the lock-forward was assisted from the ground and limped his way off. 

"You feel sorry for him, you see the expression on his face, he's filthy with what's happened," Graham said.

"It's so frustrating when you pick up an injury ... the concern and look on his teammates as well (says it all), it's such a shame. hopefully it isn't as bad as what it looks."

The Warriors went on to win the trial match 34-22.
